Step 4: Electronics

Step 5: Results

Unfortunately I have misplaced the pictures of the things I've cut with it so this instructable looks a little unfinished but there you have it!

I recently decided to try to build an RC airplane and needed a clean and effective way of cutting the foam I will be using for the plane. After some research I decided that a hot wire foam cutter would be the best solution.

I wanted something that would be able to produce clean, even, reproducible cuts so a hand help cutter was out of the question. I ended up going with a band-saw type of design.

Step 2: Main Structure

The first thing to do is to create the main wooden structure. There isn't much to explain here as it is a very simple structure but I have included a sketch of the plans I made.

The only thing I did a bit different was that I made the "mast" and overhanging beam removable for easier storage. I did this by screwing a metal plate onto the mast and then bolting the metal plate onto the base. This way I can just remove the nuts off the bolts and slide the plate off along with the arm and support.
